Abstract
The utility model relates to a driving device for the rear wheel axle of a boosting bicycle, belongs to a driving mechanism device of a bicycle, and is composed of a gasoline engine installed on the central point of a bicycle wheel and an axle tube component (9) of a bicycle. The gasoline engine is transmitted by two pairs of cylindrical gears. The output shaft (7) of the gasoline engine is connected to the rear axle tube component (9) by an integral key. Motive power is transmitted to the rear wheel of a bicycle. Compared with other rear wheel axle driving devices, the driving device has the advantages of simple structure, high efficiency, low cost, easy maintenance and easy popularization, and a general bicycle wheel can be adopted by the driven rear wheel.
Description
The utility model belongs to a kind of morpet mechanical drive,
Bicycle is particularly one of vehicle of using always of China people of people.Along with the raising of people's living standard, the quickening of rhythm of life has now occurred a kind of walking-replacing tool between trail bike and bicycle again, promptly installs the morpet of a servo-unit on bicycle additional, purpose such as, raising speed laborsaving to realize.Present this morpet has chain gear, friction wheel transmission and hind axle through-coupling several from their dynamic structure form.Problems such as wherein the morpet chain of chain gear is fragile, and driving efficiency is low, and formative nature is relatively poor, and the friction wheel transmission also exists driving efficiency low, easily skids, and tire is easy to wear.From the transmission of power angle, the hind axle through-coupling has remarkable advantages.But the present direct drive morpet of hind axle, mechanism's complexity mostly, the manufacturing cost height can not be accepted by the current great majority of China rely on the rank-and-file employees of monthly pays life.For example: West Germany SACHS30 morpet, its motogas machine is installed in the trailing wheel center, and by the worm and gear transferring power, the rear wheel steel ring adopts integral die-cast, and spark ignition engine and wheel all require manufacturing equipment precision height, thereby the productive costs height.A kind of morpet of China and for example, its motogas machine also is installed in the trailing wheel center, all adopt gear transmission, the mechanical efficiency height, but it uses epicyclic gear transmission and is installed in the rear axle tube accuracy requirement height, complex structure, the manufacturing cost height also not really adapts to the most of people's lives needs of current China.
The purpose of this utility model is to provide a kind of hind axle direct drive that both adopted, and simultaneously structure is simpler, and lower cost is easy to the hind axle actuating device of the morpet that adopted by broad masses.
Technical solution of the present utility model is as follows:
A kind of morpet hind axle actuating device, formed by a spark ignition engine and a bicycle rear axle duct member that is installed in bicycle rear wheel center, the bicycle rear wheel rotates on hind axle by the rear axle tube parts, it is characterized in that: spark ignition engine is installed in an end of hind axle, the output sleeve of spark ignition engine is contained on the hind axle, and connect by spline is relevant, thereby give the bicycle rear wheel with the spark ignition engine transmission of power with the rear axle tube parts.
The spark ignition engine of this bicycle rear axial brake device can be the output gear body with two pairs of spur gear drives, the output shaft of spark ignition engine, and its mouth has female splines, with transferring power.
The rear axle tube parts of this bicycle rear axial brake device can be that the floral disc and the purpose made cydariform floral disc of bicycle general-duty rear axle tube and one fastening with it formed, one end of cydariform floral disc has steel wire to be connected with the rear wheel steel ring, the other end has male splines, cooperate with the female splines of output shaft of gasoline engine, with transferring power.
The utlity model has than the more obvious advantage of existing morpet: because its adopts hind axle direct drive, the mechanical efficiency height, it is comfortable, clean to drive the people; Running part adopts the two-stage cylindrical wheel, exempted the manufacturing issue that brings with complicated parts such as planetary wheel and worm and gear and integral die-cast wheels, rear wheel can adopt general cycle wheel, only need to change a part that connects with spark ignition engine, as the cydariform floral disc, thereby reduced cost, and simple in structure, be easy to safeguard and promote.The utility model has been manufactured experimently model machine, proves through test run, and effect is fine.
Accompanying drawing is embodiment of the present utility model.
The left side is the spark ignition engine cutaway view among the figure, and the right side is the rear wheel cutaway view.(1) is cylinder cover, (2) be cylinder, (3) be crankshaft-connecting rod mechanism, (4) be the bent axle driving gear, the power that spark ignition engine produces passes to the clutch gear (5) that is installed on the secondary axle through bent axle by bent axle driving gear (4), passing to the spark ignition engine output gear that is installed on the hind axle (13) through secondary axle output gear (10) again is output shaft (7), the right-hand member of output shaft (7) has female splines, male splines engagement with the cydariform floral disc (11) of rear axle tube parts (9) one ends, give rear wheel with transmission of power, drive morpet and travel.
Claims (3)
1, a kind of morpet hind axle actuating device.Formed by a spark ignition engine and a bicycle rear axle duct member that is installed in bicycle rear wheel center, the bicycle rear wheel is gone up rotation by rear axle tube parts (9) at hind axle (12), it is characterized in that: spark ignition engine is installed in an end of hind axle (12), the output shaft of spark ignition engine (7) is sleeved on the hind axle (12), and links by spline with rear axle tube parts (9).
2, morpet hind axle actuating device according to claim 1 is characterized in that spark ignition engine with two pairs of spur gear drives, and the output shaft of spark ignition engine (7) is exactly its output gear, and mouth has female splines.
3, morpet hind axle actuating device according to claim 1, it is characterized in that rear axle tube parts (9) are made up of the floral disc (13) and the purpose made cydariform floral disc (11) of bicycle general-duty rear axle tube and one fastening with it, one end of cydariform floral disc (11) has steel wire to be connected with the rear wheel steel ring, the other end has male splines, cooperates with the female splines of output shaft of gasoline engine (7).
